If a child develops encephalitis, it is definitely recommended that they be hospitalized for treatment. It is necessary to assess their condition and determine the cause of the encephalitis: is it viral? Bacterial? Or caused by other pathogens? If encephalitis occurs, aggressive treatment is certainly required. In such cases, if the child is discharged from the hospital, they must regularly revisit the hospital for follow-up examinations, and the development of the child's nervous system must be monitored, focusing on motor and cognitive development. Regular assessments at the hospital are definitely required.

How to check for encephalitis?

To check for encephalitis, the main aspects of examination include the following. First, a complete blood count is necessary, which helps to determine if there is an increase in white blood cells and to assess the proportion of various types of white blood cells; this is a basic test. The second examination is an electroencephalogram (EEG), if the EEG shows abnormalities, it may suggest a diagnosis of encephalitis. The third examination involves cranial magnetic resonance imaging (MRI). If the encephalitis is severe, the MRI can reveal lesions, which also suggests a diagnosis of encephalitis. The fourth examination is invasive, involving a lumbar puncture. This test allows for the analysis of cerebrospinal fluid, assessing whether there is an increase in white blood cells and proteins in the fluid, which plays an important role in the diagnosis of encephalitis. In summary, diagnosing encephalitis necessitates a complete blood count, cranial MRI, analysis of cerebrospinal fluid, and a comprehensive EEG examination.

Encephalitis belongs to which department?

Encephalitis is primarily a neurological disorder and is an infectious disease of the central nervous system, mainly diagnosed and treated in neurology. There are many causes of encephalitis, with viral encephalitis being the most common. For example, herpes simplex encephalitis is a typical type seen clinically. Patients may experience fever, even with very high temperatures exceeding 40°C, headaches, nausea, and vomiting. If the condition worsens, seizures, coma, and cognitive impairment may occur. These clinical manifestations require further investigations like electroencephalography, cranial MRI, and lumbar puncture. Additionally, there is a specific type of epidemic, known as Japanese encephalitis, which falls under the category of infectious diseases due to its contagious nature.

What tests are conducted for encephalitis?

First, it is generally necessary to conduct an EEG test. This test is very convenient and non-invasive for patients. If significant slow waves are detected, encephalitis cannot be ruled out. Secondly, an MRI of the brain should be performed. If the viral encephalitis is severe, abnormal signals can be observed in areas such as the frontal lobe, temporal lobe, and hippocampus on the MRI, which are of great diagnostic reference value. Thirdly, lumbar puncture is also very important. It allows for a direct observation of the color of the cerebrospinal fluid, to monitor the pressure of the brain fluid, and to test the cerebrospinal fluid for cell count, protein, sugar, and chloride levels. These tests are very important for the diagnosis and differential diagnosis of encephalitis.

How is encephalitis caused?

Encephalitis generally occurs when pathogens invade the central nervous system of the brain, resulting in corresponding clinical manifestations. Patients may exhibit symptoms such as headache, fever, nausea, vomiting, and even paralysis of limbs and cognitive impairments. Patients become confused, with reduced computational and comprehension abilities. Some may also exhibit psychiatric symptoms and even experience seizures and other manifestations of epilepsy. Encephalitis is caused by pathogens, commonly viruses. Viral infections that lead to what is known as viral encephalitis can spread through the bloodstream to the brain and cause illness. Additionally, bacterial infections can also cause encephalitis. There are mainly two routes for bacterial infections: one is through bloodstream transmission leading to inflammation of the nervous system, and the other can occur directly, for example, from inflammation of the mastoids, tonsils, or cavernous sinus, where bacteria directly invade the brain, leading to the respective clinical manifestations. Furthermore, tuberculosis can also infect and cause tuberculous encephalitis, meningitis, and similar conditions.
